The following procedure guides you through multiple actions that may solve this print image quality problem. Proceed one step at a time until the problem is solved—you may not need to complete the entire procedure. If one of the steps in this procedure corrects the problem but the identical problem returns in less than 50 prints, call for service.

1.Open the paper trays and check to see if there is any toner inside the trays. If there is toner inside a tray, remove and clean the trays, then replace the paper with clean paper.

A paper jam can cause a small amount of toner to contaminate a paper tray.

2.Print 10 blank pages.

Printing blank pages can clean the printer system of small amounts of toner that may have contaminated the paper path as a result of a recent paper jam.

3.Remove the toner cartridge and inspect it for small pieces of paper that might be stuck between the drum and the toner cartridge frame. Carefully remove the pieces of paper. If you cannot remove the paper, replace the toner cartridge with a new one.

When you clear a paper jam, a piece of paper may tear off and lodge between the drum and the toner cartridge frame. This paper scrap creates a channel that allows toner from the clean- ing system to leak out onto paper as it passes through the printer.

4.Call your service technician.

This image quality problem may be caused by a malfunctioning or broken component that requires service.
